The U.S. Army Corps of Engineers Louisville District is continuing work on the Dam Safety Rehabilitation project at Rough River Lake, Falls of Rough, Kentucky. Repairs are necessary to ensure the dam continues to function as it was designed. Currently, the Corps is working on the Phase 1B contract in which holes are drilled into the bedrock of the dam and grout is “injected” into voids. The yellow silos store cement and powdered bentonite which, along with water, are the primary ingredients in the grout. The exploratory drilling and grouting program helps define future repairs and improves the foundation conditions until the final repairs can be made.
More than 100 piezometers provide data to monitor water levels in and below the dam.
The Corps conducted a public meeting in March at the Rough River State Park where Corps staff from the district office and Rough River Lake explained the condition of the dam and a possible timeline for the next phase of the project.
